    * Energy quality
  Fuel quality is a rough measure of how easy it is to transform the
- fuel into usable energy. Oil in particular has a very high quality,
- due to its high energy density and being a liquid. Sometimes it is
- worth performing an operation with low EROEI if it creates a fuel with
+ fuel into usable energy. Petroleum in particular has a very high quality,
+ due to its high energy density and being a liquid. A negative EROEI may be worthwhile if it creates a fuel with
  a higher quality -- e.g. turning coal into oil.

  In essence that energy is neither created nor destroyed, but is
